I was very confused about selecting the best practice test website when preparing for my 200-310 certification exam. Luckly, a friend told me about Lead2pass.com. I passed the 200-310 exam from the first try. Excellent website for free exam dumps!

QUESTION 42What is the primary consideration when choosing a routed network design over a traditional campus network design?

A. Layer 3 service support at the network edgeB. the routing protocol choice: open (OSPF) or proprietary (EIGRP)C. the routing abilities of the host devicesD. the need to control the broadcast domains within the campus core

Answer: A

QUESTION 43Which statement is tru

200-310

e concerning the data center access layer design?

A. The access layer in the data center is typically built at Layer 3, which allows for better sharing of services across multiple servers.B. With Layer 2 access, the default gateway for the servers can be configured at the access or aggregation layer.C. A dual-homing NIC requires a VLAN or trunk between the two access switches to support the dual IP addresses on the two server links to two separate switches.D. The access layer is normally not required, as dual homing is standard from the servers to the aggregation layer.

A. With Layer 3 at the aggregation layer, the physical loops in the topology must still be managed by STP.B. The boundary between Layer 2 and Layer 3 must reside in the multilayer switches, independent of any other devices.C. A mix of both Layer 2 and Layer 3 access is the most optimal.D. In a small data center, the aggregation layer can connect directly to the campus core, exchanging IP routes and MAC address tables.

Answer: C

QUESTION 45When considering the three VoIP design models – single site, centralized multisite, and distributed multisite – which question below would help to eliminate one of the options?

A. Will the switches be required to provide inline power?B. Will users need to make offsite calls, beyond the enterprise?C. Will users require applications such as voice mail and interactive voice response?D. Are there users whose only enterprise access is via a QoS-enabled WAN?

Answer: D

QUESTION 46With deterministic Wireless LAN Controller redundancy design, the different options available to the designer have their own strengths. Which statement is an example of such a strength?

A. Dynamic load balancing, or salt-and-pepper access point design, avoids the potential impact of oversubscription on aggregate network performance.B. N+N redundancy configuration allows logically grouping access points on controllers to minimize intercontroller roaming events.C. N+N+1 redundancy configuration has the least impact to system management because all of the controllers are colocated in an NOC or data center.D. N+1 redundancy configuration uses Layer 3 intercontroller roaming, maintaining traffic on the same subnet for more efficiency.

Answer: B

QUESTION 47When there is a need for immunity to EMI for connecting locations that are greater than 100 meters apart, which two solutions can be utilized? (Choose two.)

QUESTION 52When designing a new enterprise campus network, what topology should be used for maximum scalability?

A. flatB. three-layerC. starD. partial meshE. full mesh

Answer: B

QUESTION 53A spanning tree topology can be simplified by deploying what Cisco IOS technology in the distribution block?

A. VDCB. vPCC. Rapid PVST+D. VSSE. Flex Links

Answer: D

QUESTION 54An organization is deciding what routing protocol to use throughout their network. What must be considered if routing is to be performed at the access layer?

A. reduced scalability of the network when introducing a large number of switch blocks into the routing tableB. centralized management of access control lists at the distribution layerC. reliability when implementing routing over spanning-tree at the access layerD. performance differences between core, distribution and access layer equipment
